How to do the anti-corrosion work of thick-walled seamless tube?
The general application of thick-walled seamless tubes must do the corresponding anti-corrosion and anti-rust treatment work. The general anti-corrosion work is divided into three processes: 1. Anti-rust treatment of pipes. Before painting, the surface of the pipeline should be cleaned of oil, sl...Read more -
Precautions for spiral steel pipe stacking
Spiral pipe (SSAW) is a spiral seam carbon steel pipe made of strip steel coil as raw material, often warmly extruded, and welded by automatic double-wire double-sided submerged arc welding process. It is mainly used in water supply engineering, petrochemical, chemical, electric power, agricultur...Read more -
Production process of carbon steel welded pipe
Carbon steel welded pipes are mainly divided into three processes: electric resistance welding (ERW), spiral submerged arc welding (SSAW) and straight seam submerged arc welding (LSAW). The carbon steel welded pipes produced by these three processes have their own positioning in the application f...Read more -
